This invention relates to an improved stock lifting hook.

The stock liftin hook oi the present invention is adapted to be attachedto a hoist and inserted into a coil of wire, roll of metal or slid undera stack of bars or rods for the purpose of lifting and transporting themfrom one location to another.

It is among the objects of the present invention to provide such a stocklifting hook with adjustable means by which it is attachable to a hoistso that the center of gravity of the unloaded or the loaded hook may bevaried to maintain balance.

Further objects and advantages of the present invention will be apparentfrom the following description, reference being had to the accmpanyingdrawings wherein a preferred embodiment of the present invention isclearly shown.

In the drawings:

Fig. 1 is a perspective view of the lifting hook in one position ofadjustment;

Fig. 2 is a similar perspective view showing the hook in anotherposition of adjustment;

Fig. 3 is a plan view of the hook;

Fig. 4 is a side View of the hook; and

Fig. 5 is a front view of the hook.

The stock lifting hook of the present invention may be constructed inseveral ways. As

illustrated, the hook consists of two C-shaped beams each having avertical body portion and two horizontal, substantially parallel armsrigidly held in side by side spaced relation by rigid spacing ribsanchored to both beams. In the present construction both beams areidentical and for the sake of brevity only one will detailedly bedescribed. Beam 2:) is made of an I-beam bar bent at 2| to form ahorizontal arm 22 and a vertical body portion 23. As shown, arm 22 isabout three-fourths the length of the body portion. However, theselengths may vary with the type of hook desired. The web H) of the beamat the bend 2!, is reenforced by two plates 2 and 2E contoured to fitbetween the inner and outer flanges 2S and 2'! of the beam and againstthe web, said plates being welded to the beam and thus providing astiffening support at this bent area of said beam 20. The end of thebody portion 23 of beam 23 is also stiffened and reenforced by plates 28and 29 Welded to the corresponding inner and outer edges of the flanges26 and 21.

At the end of the body portion 23 of the beam, the web i9 is cut awayfor substantially onehalf the length of the reenforcing plates 28 and 3Claims. (Cl. 294-82) 29 in order to permit comparatively heavy mountingblocks 3t and 3! to be welded to the inside of flanges 2'1 and 26respectively. Aligned holes are provided in the flanges 25 and 27 andtheir attached blocks 3! and 39. The angular end 32 of an arm having aportion 33 substantially parallel with arm 22 of beam Zil, fits betweenblocks 3E, and Si and is immovably attached to the body portion 23 ofbeam 29 by a bolt 34. The arm portion 38 is longer than arm 22 of beam26, the upper and lower surfaces of said portion 33 converging to form atapered end on said portion 33.

The other beam is is identical with beam and has a horizontal arm 22, abody portion 43 and a second arm it. Beams 2t and 4&3 are rigidly heldin side by side spaced relation by a plurality of rigid spacer ribs 45,d6, til and 48, the ends of which are welded to the respective beams.Ribs t5 and 36, as shown in Figs. 1 and 2 are welded between the bodyportions of beams 28 and to and ribs 37 and :38 are welded between thehorizontal arm portions 22 and 42 of beams 29 and as respectively. Ribi! is Welded to arms 22 and 42 adjacent the ends of reenforcing plates2- 1 and while rib 48 is welded to arms 22 and 2 at their outer ends.Centrally apertured brackets 49 and 58 are attached to ribs 47 and itrespectively for receiving a balancing attachment bar 5! which isslidable in said brackets so as to be movable longitudinally of arms 22and 32 in order to adjust the loop element 52 attached to bar 5i inaccordance with the center of gravity of the hook or the load supportedby the hook. The loop element 52 may be integral with bar 5! or, asillustrated, it may be an apertured plate Welded to said bar.

Bar 51 has two pairs of notches E i- 55 and 5t--5l spaced the same asbrackets 29 and 56 so that when the bar is moved as in Fig. l, bracket39 engages notch 55 bracket 5% will engage notch and when bar 52 isadjusted so that notch is engaged by bracket iii), the notch 5'! will beengaged by bracket it. This looks bar ill against longitudinal movement,in one instance with the loop member t2 adjacent bracket 29 and in theother instance with the loop member 52 adja cent the bracket 58. Thusthe bar 5! is selectively adjustable into different positions relativelyto the hook to compensate for shifting of the center of gravity due toloading of the hook. If necessary more pairs of notches may be providedin bar 5! offering a greater number of selective positions into whichbar all may be moved relatively to the hook.

Fig. 1 shows the hook in the normal, no load balanced position. Here thebar 5| is so positioned that the loop member 52 thereof is ad- J'acentthe bracket 49 so that the greater portion of the arms 22 and 33 are toone side of the center of gravity while the smaller portions of saidarms and the body portion 23 of the hook are to the other side of thecenter of gravity. Thus the hook when suspended from the hoist has itsarms 22 and 33 substantially horizontal and its body portion 23vertical.

As shown in Fig. 2, the hook, when suspended with the loop member 52adjacent the bracket 50, will assume a tilted position. This isdesirable when the hook is loaded for in this position of adjustment theload on the hook will be urged toward the body portion 23 and thus thetendency of the load to roll or shift ofi the hook is substantiallyreduced due to this shifting of the center of gravity.

Thus the present invention provides a simply constructed and sturdy loadlifting hook easily adjusted for initial application to the loadpreparatory to lifting thereof and readjusted just as easily forshifting the center of gravity whereby the load is urged into the hookto prevent dropping of the load during lifting and transporting.

While the embodiment of the present invention as herein disclosed,constitutes a preferred form, it is to be understood that other formsmight be adopted.

What is claimed is as follows:

1. A stock lifting hook for engaging and transferring loads, consistingof two C-shaped beams held side by side in spaced relation by rigid ribsattached to the horizontal and vertical arms of said beams; and abalance bar longitudinally, shiftably supported between two of the rigidribs secured between the upper two horizontal arms of said beams, saidbar having a hoist-hook receiving loop and a plurality of pairs ofspaced notches engageable with notch receiving edges on said ribs forlocking the bar thereby in a selected position against longitudinalmovement relatively to said ribs.

2. A stock lifting hook for engaging and transferring loads, consistingof two C-shaped beams held side by side in spaced relation by rigid ribsattached to the horizontal and vertical arms of said beams; two adjacentribs being positioned between the upper two horizontal arms of saidbeams, said adjacent ribs having openings midway between said horizontalarms to which the said ribs are attached; a balance bar extendingthrough said openings of said ribs and being longitudinally movable insaid openings, said bar having pairs of notches engageable with theedges of said ribs around said openings for locking said, bar inselected positions against longitudinal movement relatively to saidribs; and a hoist-hook receiving loop member attached to the bar andpositioned between the supporting ribs.

3. A stock lifting hook for engaging and transferring loads, said hookconsisting of two rigid beams each shaped to provide an upper horizontaland a vertical arm, said beams being secured together in side by side,spaced relation by a plurality of spacer ribs secured between thehorizontal and vertical arms of said beams, two adjacent ribs betweenthe two upper horizontal arms of the beams each having an opening midwaybetween said beams; a rigid load supporting member removably secured tothe vertical arm of each beam and having a portion parallel to thehorizontal arm of the respective beam; a balance bar slidably supportedin the openings of said two adjacent ribs so as to be longitudinallymovable relatively to the horizontal arms of the beams; pairs of notchesin the bar each pair spaced so as to receive the edges around theopenings of said two adjacent ribs for locking the bar in a selecte'dlongitudinal position relatively to said ribs; and a loop memberprovided on the bar and extending from the hook between the horizontalarms and the two adjacent ribs engaged by the bar.
